THILL-COUPLI NG.

SPECIFICATION forming part of Letters Patent N 0. 352,517, dated November 16, 1886. Application filed September 1, 1886. Serial No. 212,404. (No model.)

To all whom it may concern.-

'Be it known that I, DANIEL B. CAHOW, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a new and useful Improvement in Thill-Couplings, of which the following is a specification.

My invention relates to an improvement in thill couplings; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of a thill-coupling embodying my improvements. Fig. 2 isa vertical longitudinal sectional View of the same. Fig. 3 is a vertical transverse sectional view" taken on the line 00 x of Fig. 2.

A represents the shackle or clip, which is adapted to be attached to the front axle of the vehicle. In the. upper and the lower sides of the shackle are vertical aligned openings B, and in the sides of the said shackle are the semicircular curved slots G,'which are open at their upper ends on the front side of the shackle. These slots 0 communicate with the openings B at about the center thereof.

, D represents the draft-iron of the thills, which is provided at its inner end with an eye, E, that is adapted to fit between the sides of the shackle. From the center of the eye, at the ends thereof, project trunnions E, which are adapted to enter the open-ended slots 0, so'as to secure the draft-iron to the shackle, as will be very readily understood.

G represents a flat plate, which is passed vertically through the openings B, and bears against the rear side of the eye of the draftiron. The upper and lower ends of the saidplate are bent at right angles, as at g, and bear upon the upper and lower sides of the shackle, so as to prevent vertical displacement of the plate.

H represents a wedge-shaped key, which tapers toward one end and is provided at the larger end with a head, It. In the lower end of the key is made a transverse opening, h.

'The said key is inserted in the openings B of the shackle, and bears against the rear side of the plate G, so as to force the latter firmly against the rear side of the eye of the draftiron', and thus retain the trunnions thereof in the lower closed ends of the slots 0. This prevents the thills from becoming accidentally detached, and also prevents rattling. As the key is wedge-shaped, it may be driven down in the openings B of the shackle, so as to take up wear. A pin is inserted in the opening h at the lower end of the key for the purpose of preventing the latter from becoming accidentally detached from the shackle.

A thill coupling thus constructed is exceedingly cheap and simple, is very strong and durable, prevents rattling, and enables the thills to be readily attached to the vehicle or detached therefrom.

Having thus described my invention, I claim- In a thill-coupling, the shackle having the openings B and the curved slots 0, which are open at their upper ends on the front side and are closed at their lower ends, said slots 0 communicating with the openings B, in combination with the draft or thill iron D, having the eye seated in the slots 0, the plate G, passed through the openings B and bearing against the outer face of the eye of the thilliron, and the wedge H, also passed through the openings B, to keep the plate G pressed against the outer surface of the thill-eye, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses. Y

DANIEL B. OAHOW.
